Abstract: Using simple quantitative methods based on the concepts of exchange field, Dzyaloshinsky field and magnetic anisotropy field, the effect of lanthanum substitution by strontium on the main macro- and microscopic magnetic characteristics of La$_{1-x}$Sr$_x$FeO$_{3-\delta}$ was assessed.

Keywords: substituted lanthanum orthoferrites, canted antiferromagnetism, vacuum annealing.
